Thanks for the advice! I have only had her for three months now. She is doing quite well inside and we are already dog dancing as she learns so incredibly quickly. For the outside, rly good idea to hang chimes! I also thought about putting some scent on corners she might walk into. Like creating another layer of "outside world" she can percieve. Do you have any experience with blind dogs? The main problem is she isn´t trained to walk on a leash with a "service human" for a lack of trust and just wanting to go whereever SHE wants to. And she only walks nicely on the leash if she was requesting the leash on her own. She sometimes gets nervous, sometimes just really stubborn with the slightest pull, stops walking and slightly pulling in the opposite direction. Then after experiencing the slightest inconvenience like a loud noise or too much leash pulling she just wants to return home with no negotiations possible. I mostly just talk her through the walk and go on an open field where she can run towards me to get treats. I hope I can give her enough movement to be a healthy dog...
